 * @classDescription The base function which all other series types inherit from. The data in the series is stored
 * in various arrays.
 *
 * - First, series.options.data contains all the original config options for
 * each point whether added by options or methods like series.addPoint.
 * - Next, series.data contains those values converted to points, but in case the series data length
 * exceeds the cropThreshold, or if the data is grouped, series.data doesn't contain all the points. It
 * only contains the points that have been created on demand.
 * - Then there's series.points that contains all currently visible point objects. In case of cropping,
 * the cropped-away points are not part of this array. The series.points array starts at series.cropStart
 * compared to series.data and series.options.data. If however the series data is grouped, these can't
 * be correlated one to one.
 * - series.xData and series.processedXData contain clean x values, equivalent to series.data and series.points.
 * - series.yData and series.processedYData contain clean x values, equivalent to series.data and series.points.
